Introduction

1.3Tornado* for I20* Software Development Toolset

Tornado for I20 is a complete toolset featuring an integrated development environment including a compiler, assembler, linker, and debugger. It also features a real-time operating system.

1.3.1IxWorks* Real-Time Operating System

The IQ80960RM/RN platforms are equipped with Wind River Systems, Inc.’s IxWorks*. IxWorks provides for the elements of the I2O standard: an event-driven driver framework, host message protocols, and executive modules for configuration and control. IxWorks also allows for the writing of basic device drivers and provides NOS-to-driver independence. TORNADO for I2O provides a visual environment for building, testing and debugging of I2O drivers.

1.3.2TORNADO Build Tools

TORNADO for I2O includes a collection of supporting tools that provide a complete development tool chain. These include the compiler, assembler, linker and binary utilities. Also provided is an I2O module builder, which creates I2O-loadable modules.

1.3.3TORNADO Test and Debug Tools

TORNADO for I2O test and debug tools include the dynamic loader, the CrossWind∗ debugger, the WindSh* interactive shell, and a system browser.

The dynamic loader allows for interactive loading, testing, and replacement of individual object modules that comprise a driver.

CrossWind is an extended version of GDB960. Using it you can debug I2O drivers by setting breakpoints on desired I2O components. A variety of windows display source code, registers, locals, stack frame, memory and so on.

WindSh allows you to communicate to the IQ80960RM/RN platform via an RS-232 serial port. The IQ80960RM/RN platform supports port speeds from 300 to 115,200 bps. The shell can be used to:

•control and monitor I2O drivers

•format, send and receive driver messages

•examine hardware registers

•run automated I2O test suites

The shell also provides essential debugging capabilities; including breakpoints, single stepping, stack checking, and disassembly.
